Performance analysis of energy-harvesting-aware multi-relay networks in Nakagami-m fading

Abstract

This paper investigates the outage performance of an energy-harvesting(EH) relay-aided cooperative network, where the source node transmits information to its destination node with the help of multiple energy-harvesting cooperative nodes. For such a system, we derive an explicit closed-form expression of outage probability over Nakagami-m fading channels, where the on-off EH model is considered. We simulate the explicit closed-form expression of outage probability with different parameters compared with the related Monte Carlo method. It is shown that the simulation results match well with the numerical ones, which demonstrates the correctness of our theoretical analysis. It indicates that to evaluate the system outage performance, our theoretical results can be applied without running the complex Monte Carlo simulation. Via simulations, it is observed that the system outage performance will be improved when natural source EH relays are employed. Besides, more relays, better system performance.

“…Satellite communication (SatCom) has the potential of providing connectivity for fixed and mobile users especially in the areas where the terrestrial networks are challenging or infeasible to be deployed [1][2][3][4]. Meanwhile, it has been shown that relay technology is able to offer significant performance benefits, such as improving the system throughput via spatial diversity, extending signal coverage without consuming large transmitter power [5]. Therefore, the application of relay transmission in SatCom has been an active research topic both in academia and industry recently.…”

“…S. Zhong et al investigated the outage performance of an EH relay network in which the BS transmits information to the SNs with the help of multiple ERs by using the AF technique. These authors concluded that the outage performance of the system can be improved by employing EH ERs [25].…”

“…An SN can collect energy from ambient RF signals to power its operations. RF EH is especially attractive for relay WSNs that rely on ERs to extend their coverage areas and improve their system performance [23]- [25]. For instance, A. Nasir et al considered the application of RF EH in relay WSNs based on two practical receiver architectures for EH, namely, time-switching-based relaying (TSR) and power-splitting-based relaying (PSR) [23].…”
